The UPS, including Bypass, remains off until restarted.
All power to the critical load is lost when the REPO switch is activated in the following step. You should use
this feature only when you want to de–energize the critical load.
NOTE
The following instructions are for the Eaton-supplied REPO switch. If a customer-
supplied REPO switch is used, it may not activate in the same manner; refer to the
operating instructions provided with the switch.
To use the REPO switch:
1.
Firmly push the red pushbutton until it locks into place. The switch latches into the activated state (see
).
The input, output, and bypass backfeed contactors open, the battery breaker or disconnect is tripped, and
the power module is turned off immediately, without asking for verification.
Do not attempt to restart the system after the REPO until the cause of the shutdown has been identified and
cleared.
2.
To deactivate the REPO switch in preparation for restarting the UPS, insert the supplied key and rotate
clockwise until the red pushbutton releases (see
). To remove the key, rotate the key back to the
vertical position.
3.
